lMPROVEMENT IN BRAKE-LEVERS.

Specification forming part of Letters Patent N 0. 194,926, datedSeptember 4, 1877; application filed July 28, 1877.

To all whom it may concern:

Be it known that I, WILLIAM F. OSBORN, of Burlington, in the county ofCoffey and State of Kansas, have invented a new and valuable Improvementin Brake-Levers; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a plan view of mybrake-lever, and Figs. 2,

3, 4, 5, and 6 are details thereof.

The nature of my invention consists in the construction and arrangementof a device for operating wagon-brakes, as will be hereinafter morefully set forth.

The annexed drawing, to which reference is made, fully illustrates myinvention.

A represents the side of a wagon box or body, to which the segment B isattached by means of screws or pins a a at the corners. Along the innercircumference of the segment B are formed ratchet-teeth 12,substantially as shown.

The lever for applying the brake is made in two parts, 0 and O, thelower part, 0, being pivoted by the lower screw or pin of theratchet-segment, and extending up between it and the wagon-body A. Theupper part, 0, of the lever is pivoted to the lower part, 0, and whenstanding on a line therewith rests against a projectinglug or shoulder,d, on said lower part 0. To this lower part (J is pivoted a pawl, D,which, by means ofa spring, 6, is thrown into gear with the ratchet b,arranged on the under side of the segment B.

The lower end of the upper part 0 of the lever is provided with a cam orcam-arm, h, which, when said part is thrown forward, releases the pawlt'rom the ratchet-segment and releases the brake. As soon as the forwardpressure of the part 0 of the lever is removed the spring 6 at oncethrows the pawl D into the ratchet, again holding the same in place.

I am aware that a curved ratchet-bar and a lever with an engaging-pawlhave heretofore been used; and I therefore lay no broad claim to suchinvention; but

What I claim as new, and desire to secure by Letters Patent, is-

In a wagon-brake, the combination, with the segment B, havingratchet-teeth on the under side, of the single-jointed lever O C, theupper part, C, of which is provided with a cam, h, and the lower part,0, having attached thereto a pivoted paw], D, and spring 6, allconstructed and operated as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM FAIRGHILD OSBORN.
